That's your problem right there. If you connect your iPhone to your car's USB socket, the Uber app will not sound.

Are there any ways around this (settings)? I have the same issue (no ping sounds) when my car is running. Thanks

Yes, don't plug your phone into your car's USB.

Buy a cigarette lighter socket charger to charge your phone and connect audio via Bluetooth or aux cable.

Beauty! Thanks for the advice!!
